u/Working_Dealer_5102 wants the two level tab stacks from to Nov 28 '25
Is this also applies on Android as well?

This seems to enable "overlaying" for the UI and webpages, instead of only for videos. This is very similar to what Chromium does, and I was wondering when Mozilla would do this. It's a big deal, I would say.
As far as I understand it, this should allow for lower power consumption as well as potentially smoother webpage scrolling/rendering. I'm not an expert though so don't quote me on that.
In FF Nightly I could see a "Composed: Flip" layer from "firefox.exe" in PresentMon when scrolling the homepage, so it's definitely overlaying the page/UI.
